Specification of Letters Patent. Patnted Feb, 7, 1922.

Application filed March 26, 1920. Serial No. 369,087.

(GRANTED UNDER THE PROVISIONS OF THE ACT. OF MARCH 3, 1921, 41 STAT. L, 1313 T00]? whom. it may concern:

Beit known that I, AoHEsoN FERGUSON, a subject of the King of Great Britain and Ireland, residing at Belfast, Ireland, have invented certain new and useful Improvements in and Relating to Blocks Used for Building Purposes, (for which I filed an application in Great Britain J an. 18, 1918,

' Patent No. 123,361,) of which the following is a specification.

This invention relates to blocks used for building purposes ofithe classin .which the blocks are uniform, interchangeable and reversible and have marginal recesses and corresponding interlocking projections which prevent the blocks separating when built together.

Under my invention I provide a double hooked interlocking reversible block of the class stated which is characterized by having the interlocking recesses and projections at two opposite sides and is level at the other sides so as to give, when built into a wall, a horizontal joint at every course. For making hollow walls interlocking and reversible facing blocks are provided for both portions of the wall, with transverse bonding members integral therewith which serve to bond the two portions of the wall together, the joint between the transverse members of the wall blocks being a vertical hooked joint such as will effectively prevent damp, or absorbed water, passing from the outer face of the wall to the inner portion of the wall. Preferably the bonding blocks are so arranged in each course, or are superimposed, to form a continuous vertical hooked joint between the vertical limits of the hollow wall to be bound or tied thereby. The joint may be made with any suitable water resisting material and I have found asphalts to be satisfactory, but any cheaper and equally satisfactory jointing material may be used.

In order that the invention may be clearly understood I have hereunto appended explanatory drawings showing examples of interlocking building blocks in accordance with my invention, and also showing how blocks, in accordance with my invention,-may be used, for example, in the build ing of standardized houses.

Fig. 1 is an elevation of the front wall of a house in which the new blocks are used.

Fig. 2 is a cross section of the front wall of the house on the line 2-2, Fig. 1, and showing part of the return wall.

Fig. 3 is asectional plan on the line 3 3, Fig. 1. I v

Fig. 4 is a sectional plan on the line 44, F 1g. 1. Y 1

Figs. 5 and 6 are detail views of the transverse bonding. blocks 6 Referring to the drawings In the example illustrated at Figs. 1,2 and 3 a hollow wall is built up mainly of blocks at. These blocks a have each a hook a at one side and a hook a at the opposite side, the remaining sides of the block being fiat so as to give a horizontal joint at every course, when the blocks are built into a wall, as clearly shown at Fig. 1.. The blocks a and the two portions of the wall are bound together by blocks 7), b 0, d, e, f, f and The blocks 6 are made with four hooks and are each adapted to engage four of the blocks a. The blocks b are madewith two books and are each adapted to engage two of the blocks a." The blocks 0 are also adapted to engage two of the blocks a and differ only from the blocks 6 in being a little higher for use at starting courses. The blocks 6, b and 0 have each integral therewith a projecting portion 72 which forms a vertical hooked bonding 'member so that when two such members 6 are interlocked a vertical joint is formed which prevents damp or absorbed water from passing across the bonding members in the wall. These joints formed by the portions 6 would preferably be made with a suitable water resisting material. At door and window openings blocks 03 are provided having transverse bonding portions al (similar to the portion 6 and these blocks (1 are used to interlock with blocks. 6 having transverse bonding portions 6 and blocks ,1, forming quoins are provided with transverse bonding portions 7' and interlock transversely with inner corner blocks f having corresponding portions f Where a cross wall is to be bound to the outer wall, blocks j, are provided having transverse bonding portions 9' adapted to interlock transversely with corresponding transverse bondi'ngportions b of Wall blocks 6 In each case the transverse joint is a water resisting, oint similar to the joint described with reference to blocks 12 Figs. 5 and 6 so that water which finds its way through the outer wall blocks will not be able topass into the inner wall blocks. The window jamb pieces d interlock with the front or outer wall blocks a and they also interlock transversely with the blocks 6 which form the inner jamb of the Window and interlock with the inner wall blocks a.

Having now fully described my invention WhatI claim and desire to secure by Let Wall built'with the interlocking reversible blocks, the transverse bonding members thereby.

forming a vertical hooked joint which prevents the passage of damp from the outer Wall blocks to the inner wall blocks.

2. A double-hooked interlocking reversible building blockhavin'g interlocking recesses and projections at two opposite sides and made level at the other sides so as to give a horizontal joint when built into a Wall, transverse bonding members integral with theblocks and serving to bond together the outer and inner portions of a hollow wall built with the interlocking reversible blocks, the transverse bonding members forming a vertical hooked joint which prevents the passage of damp or absorbed moisture from the outer wall blocks to the inner Wall blocks and forming a continuous vertical hooked joint between the vertical limits of the hollow Wall to be bound or tied In testimony whereofl affix my signature in presence of two Witnesses.
